For example, the secondary overgrowth quartz, authigenic illite, and authigenic ankerite on the cementation was inhibited by oil emplacement, but pyrite was mainly distributed in oil layer and oil water layer, particularly rich in oil water layer.

由于烃类的侵位，使石英的次生加大、自生铁白云石的生长受到抑制，同时也对自生伊利石生长有抑制作用，黄铁矿由于烃类侵位分布在油层、油水层，尤其在油水层中较为发育。

The author creates the AutomaticallyDiscriminational Model for the Classification of Sandstones System, thatis to say, people can complete the vastly sample s classification of sandstonesaccurately and swiftly, meantime, diminish the possibility of mortal mistake. Based on the study of the basic sandstone component before embedding, the typeof authigenic mineral, and the forming mechanism of porosity in Upper Paleozoicreservoirs in Ordos basin, the author selects the reasonable experiment objects forWater-Rock Interaction modeling study, designs the relatively reactant and resultantduring the diagenesis period, builds the solid-liquid thermodynamics model with theprinciple of thermodynamic phase equilibrium for kinds of primary minerals (potashfeldspar, albite, anorthite, and pyroxene, hornblende) which dissolve in acidic media,and forms the corresponding thermodynamics test database.

在对鄂尔多斯盆地上古生界储层砂岩埋藏前组成、自生矿物类型和孔隙构成研究的基础之上，确定合理的沉积盆地水—岩相互作用模拟研究的实验对象，设计了埋藏成岩过程有关反应的反应物和可能的生成物，并通过热力学相平衡原理，建立了碎屑岩在埋藏成岩过程中各种骨架颗粒(钾长石、钠长石、钙长石以及铁镁暗色矿物中的辉石、角闪石等)在酸性介质条件下发生溶解的固体—流体相化学反应热力学计算模型，并获得了相应的热力学数据库，在此基础上对储层砂岩中主要造岩矿物(钾长石、钠长石、钙长石以及铁镁暗色矿物中的辉石、角闪石等)在埋藏成岩过程的酸性介质条件下发生溶解的热力学习性进行了论述。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。
